摘　　要：针对机械加工领域内环槽宽度尺寸无法直接测量难题,提出一种直接同时测量内环槽直径尺寸和宽度尺寸的一体式量具设计方案。运用齿轮传动及齿轮齿条传动原理,设计测量内环槽结构尺寸的机械式量具。对样品经过验证表明:该复合测量尺能够对内环槽直径尺寸和槽宽度尺寸同时进行精确测量,操作简单方便,可填补内环槽直接精确测量的空白。In the field of mechanical processing,it is a problem that the width size of an inner ring groove can't be measured directly. A design scheme of integrated gauge that measures the inner ring groove diameter and width dimensions simultaneously is proposed. A mechanical measuring tool for measuring the inner ring groove structure size is designed using the principle of gear and gear rack transmission. The results of the test sample show that the composite measurement tool can also accurately measure the diameter of the inner ring groove and the groove width. The operation is simple and convenient. The invention is applied to the actual,and fills the blank in the field of the grooves size direct measurements precisely.
